The Colombian Navy FS-1500.
As built in the 1980s, with a very spartan equipment.
After the MLU, with new radar set, Strales 76 mm gun, south korean SSMs, and two double Mistral missile stations.
Yes, Mitchel! The lost black pixel was a remain of a moved antennae! Thanks for your advice! In the pictures, the radar looks in a lighter gray, at least in the pictures around 2013.
Thanks to Mike and Eswube! Cheers!
Already corrected! Thanks Hood!
